I'd like to believe this means he won't be going anywhere in the primary seeing as Scott Walker - the great appeaser with no ideology - had a more cohesive answer including the fact that he has attended one. I'm confident a President Walker would come out in support for before re-election. Rubio would need much more political pressure to do the right thing which says a lot considering who he's getting compared to.
What about Scott Walker makes you think he's pro same-sex marriage?
He was pretty virulently anti-gay marriage before, supporting a constitutional amendment to ban it and even trying to ban same-sex couples from visiting each other in the hospital.
All credit to Republicans that support same-sex marriage, but let's not grade on a curve. It's illogical to oppose same-sex marriage if you think being gay is an immutable characteristic and there's nothing morally wrong or shameful about it.
